问题描述
基本上这些是两个问题：
Basically these are two questions:
-
如何删除iPad的弹出视图的箭头？
How to remove iPad's popover view's arrow?
有没有办法删除popover的黑色边框？
is there any way to remove popover's black border?
如果不可能，你能在iPad上建议一种在屏幕顶部显示UIView（popover）而没有箭头和边框（可能是浅透明边框）的方法吗？非常感谢。
If not possible, can you suggest a way in iPad to display an UIView (popover) at the top of screen without arrow and border (might be light transparent border), please? thanks a lot.
我不认为ModalView是一个合适的选项，因为它无法调整大小并且无法通过单击外部模态视图来解除。
And I don't think ModalView is a proper option, as it cannot be resized and cannot be dismissed by clicking outside modal view.
推荐答案
当调用-presentPopoverFromBarButtonItem：allowedArrowDirections：时，将0作为第二个参数传递，而不是任何常量。这没有记录，但Apple在使用此设置时允许App Store中的应用程序。
When calling -presentPopoverFromBarButtonItem:permittedArrowDirections:, pass 0 as the second parameter, rather than any of the constants. This isn't documented, but Apple is allowing apps in the App Store when using this setting.
